Application filed October 4, 1912. Serial No. 723,822.

To all whom it may concern:

Be it known that I, PERCIVAL 'S. TIoE, a

citizen of the United States, residing at.

Detroit, county of Wayne, 'State of Michigan, have invented acertain new and useful Improvement in Carbureters, and declare the following to be a full, clear, and exact description of the same, such as will enable others skilled in the art to which it pertains to make and use the same, reference-being had to the accompanying drawings, which. forma part of this specification.

My invention relates tomeans for sup plyingv liquid fuel to internal combustion engines. I

In the accompanying drawings: Figure 1, is a side elevation of a portionof a multicylinder internal combustion engine with is'a plug n passing through an aperture in thehead of each of the four cylinders. e, e, e,.e, are unions connecting a plpe g with the four plugs 01..

g, is an aperture formed through each of the plugs a and communicating with the combustion chamber f of each of the 'cylln- 0, is a screw threaded plug in the upperend of the passageg.

p, indicates a very small aperture formed through the plug 0 and communicating with the passage q and thereby with the combustion chamber of the cylinders. I

m, is a reservoir for liquld fuel provided with a usual float apparatus for maintaim ing a constant level of fluid therein.

k, is a delivery spout through which fluid passes from the reservoir m, and is delivered into the intake pipe I). p

y, is a casing surrounding the spoutk leaving an annular passage as around the upper end of said spout.

h, is a pipe connecting with the pipe 9 at .the center thereof and at the lower end 'connected with a passage communicating with the interior of the caslng y.

Specification of Letters Patent.

Patented Jan. 4,1916.

The operation of the above described device is as followsz'The passage 29 through the screw plug 0 is always n open communication with the pipe 9 and therefore with the pipe 12. and the interior of the casing A pressurein the pipe 9 is therefore maintained proportional to the average pressures at any nstant in the cylinders and also influenced by the size of the an nnlar-passagepc and the speed of the engine. By the gas under this pressure, when the engine 'is working, the,

fuel is sprayed from the spout is by the action of the gases issuing in a jet out of the annular passage m and this sprayed fuel is taken up by the air passingto thecylinders.

The size of the passage, p is .a matter of design and, is' proportioned to the engine with which it is to be used. I have used passages ranging in size from that corresponding to a number sixty, to that corresponding. to a number eighty drill. This passage being so small it does not interfere with the operation of the engine and atthe same time supplies suflicient gas to the casing j to efiectivelv spray the, fuel. Asthe speed of the engine varies the spraying acing the jet for spraying the fuel being sup plied from the combustion chamber is quite hot and its heat assists the vaporization of the fuel. I

What I claim is 1. In an internal combustion engine, a working cylinder having a combustion chamber, a conduit for delivering liquid tion will be varied so that a proper mixture 1 is-automatically maintained. The'gas formfuel, a passage communicating with said combustion chamber and so located that it shall project a, jet of gas past the delivery end of said conduit so as to spray the liquid therefrom, said passage being unobstructed throughout its length and in uninterrupted connection with said combustion chamberby an aperture of such a size that the gas shall be impelled through said passage by a pressure which is the algebraic sum of the pressures in said combustion chamber.

2. .In an internal combustion engine, the

combination of a plurality of cylinders,

. each of said cylinders having a combustion chamber, a manifold, means for placing said manifold in uninterrupted connection with the combustion chamber of each of said cylinders, a conduit for liquid fuel and a passage continuously open throughout its length leading from said conduit so as to spray the liquid fuel from said conduit, the connection between said passage and combustion chamber being such that the gases shall be impelled through said passage by a pressure which is the algebraic sum of the pressures in the combustion chamber.

3. In an internal combustion engine, a working cylinder having a combustion chamber, a conduit for delivering liquid fuel, a passage communicating with said combustion chamber and so located that it shall project a jet of gas past the delivery-end of said conduit so as to spray the liquid therefrom,

meaaao said passage being unobstructed throughout its length and in uninterrupted connection with said combustion chamber, the opening from said passage into said combustion chamber and the opening from said passage through which the jet is delivered having their areas proportioned to each other so that theproper rate of delivery of fuel shall be secured under different conditions of the operation of the engine.

In testimony whereof, I sign this specification in the presence of two Witnesses.
